Hope this helped! I'm only up to Chapter X, but I have the Grammatica Latina and the Latine Disco Student's Manual supplementary booklets, and they helped. Also Ørberg's method of defining new words on the basis of words previously studied, and his extremely helpful decision to index each word with the chapter and line number where it was first introduced and defined.

I could have translated it for you into English, but that would not be Ørberg's way, so despite my poor knowledge of Latin, I tried to help you as much as possible using Ørberg's references for the most part.
